Application filed September 2 2, 1915. Serial No. 52,038.

is to provide an inexpensive, strong and durable tie which shall be better capable than known ties of resisting the'heavytrains, to which railway-ties are subjected. To aecomplish this object, I arrange the plane, connecting the under edges of the front and rear walls of the tie in such a manner obliquely, that it is nearly perpendicular to the resulting force of vertical pressure and the horizontal strain of the running train working on the tie. In this position of the tie, the whole body of ballast, pressed by the tie and supporting the tie will take up uniformly the horizontal str in to which the ties are subjected.

In the drawings several modifications of such a tie are shown.

Figure 1 shows in cross sectionan iron cross-t e according to my invention. Fig. '2 shows in cross-section a modification. having a rib for retaining the bed plate.v Fig. 3 is a cross section of a further mod fication. F gs. at and 5 show two other modifications of a tie having a cross-section of I-shape. F g. 6 shows a tie of wood or concreteaccording to my invention.

The iron tie, shown in Fig. 1, consists of the top a, the front wall I) and the back wall 0. The front wall 6 is shorter and the back wall 0 is longer than in the ties generally used, so that the plane connecting the under edges of'the frontand the back wall lies obliquely and is nearly perpendicular to the resulting force R of the vertical pressure D of the train and the horizontal strain S produced by the rolling train. The resistance of the ballast against the strains to which the tie is subjected, is therefore greater than in ties, in which the front wall and the back wall have the same length.

The tie, shown in Fig. 2, is provided on the front edge of the top a *ith a rib (Z for retaining a bed plate (not shown). A rib on the back ee ge is not necessary, as the horizontal strain, produced by the rolling train, works only in one direction.

In the mod fication of thetie, shown in Fig. 3 the r b (Z is provided with a forward projection (Z and on the back edge of the top a a similar proiection d is provided, directed backward. These projections may be engaged by well known clamping devices. connecting the rail with the bed plate and the tie.

' In Fig. t a t e is shown having an upper horizontal flat flanged and an under hori- 7ontal flange g. both connected by the web 7'. The flange is provided at its back edge with a projection (7 directed downwardly. A modification of this tie is shown in Fig.

5. The under flange is arranged obliqnely so that it lies parallel to the plane. connecting the under edges of the walls I) and c of the ties shown in Figs. '13.

In Fig. 6 a tie a of wood or concrete is shown. in which the front wall If is shorter than t e back wall 0 so that the under wall it is oblique.

Vi hat I claim and desire to secure by Letters Patent is:

1. A railway t e having its botom l ne inclined substantially perpendicular to the resultant of the forces exerted on the tie.

2. A railway t e having its bottom plane inclined upwardly in the direction of the mo ement of the load thereon and substantially perpend cular to the resultant of the forces exerted on the tie.

3. A railway tie having a top wall. a short front wall depending therefrom. and a back wall depending a greater distance from the top wall than the front wall, the lower edges of said depending Walls being in a Plane resultant of the forces exerted on the top'of perpendicular to the resultant of the forces the channel bar. exerted on' the top wall. r v

4. A railway tie consisting of a channel V V X ivlrnTOR' bar having a front depending side Wall, and Signed in the presenceof the following a rear side Wall depending a greater distance two Witnesses:

than the front Wall, the lower edges of said ELSE HOLLENWERK, Walls belng 1n a plane perpendlcular to the VICTOR Donn.
